2015 papal coins

there were several coins issued for the 2015 papal visit.. and they came out in beautiful packaging.. but many are really collectible items only because when the interest to the coins fades off their prices will go down.. for example, the 500 peso coin issued was identified as NORDIC gold, yes it is very pretty, but it would not be practical to hoard it because it may not be profitable later, but maybe yes because they say it is limited.. the silver and gold coins is yet to come out and we have to wait until May.. wish they will have a respectable silver and gold content (i mean true silver and true gold)..
